Sometimes work is boring and inefficient. While I was working on the relaunch of ClientSolutions website I had the idea to make copying of posts and pages to other languages more easy.
If you use Polylang (thanks for this great plugin) for translating your wordpress page too, you maybe interested in using my little plugin. It will add a dropdown to each row action in posts, cpt or page listings from which you can select a language to translate a post or page in. After that you will be redirected to the edit screen.
Polylang Copy makes an exact copy of the item, including featured image, categories and tags. If there are translations of categories or tags they will be used instead of original cats or tags.
